AvalonLog is a fast and thread-safe WPF text log viewer for colored text. Including F# printf formatting. Based on AvalonEditB. Works on .NET Framework 4.7.2 and .NET 7.0+

Thread-safe means that it can be called from any thread.

Fast means

• it buffers repeated print calls and updates the view maximum 20 times per second. see source

• Avalonedit is fast, the view is virtualized. It can easily handle thousands of lines.

Use with F#

Here an short example for F# interactive in .NET Framework. (for net9 you would have to use it in a project)

#r "PresentationCore"
#r "PresentationFramework"
#r "WindowsBase"

#r "nuget: AvalonLog"

open System.Windows

let log = new AvalonLog.AvalonLog() // The main class wrapping an Avalonedit TextEditor as append only log.

// create some printing functions by partial application:
let red = log.printfColor 255 0 0 // without newline
let blue = log.printfnColor 0 0 255 // with newline
let green = log.printfnColor 0 155 0 // with newline

// print to log using F# printf formatting
red "Hello, "
blue "World!"
red "The answer"
green " is %d." (40 + 2)

Application().Run(Window(Content=log)) // show WPF window

this will produce

👁 WPF window

Use in C#

public void AppendWithBrush(SolidColorBrush br, string s)

and similar functions on the AvalonLog instance.
